Summary:
With the XCode project gone, there doesn't seem to be anything setting
this macro anymore -- and the macro wasn't doing much anyway.

This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.
find . -type f -name '*.cpp' -exec \
sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +

operator new doesn't return a null pointer, even if one turns off
exceptions (it calls std::terminate instead). Therefore, all of this is
dead code.

This is the second patch to improve module loading in a series that started here (where I explain the motivation and solution): https://reviews.llvm.org/D62499
I need to read the aux vector to know where the r_debug map with the loaded libraries are.
The AuxVector class was made generic so it could be reused between the POSIX-DYLD plugin and NativeProcess*. The class itself ended up in the ProcessUtility plugin.

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

The `ap` suffix is a remnant of lldb's former use of auto pointers,
before they got deprecated. Although all their uses were replaced by
unique pointers, some variables still carried the suffix.
In r353795 I removed another auto_ptr remnant, namely redundant calls to
::get for unique_pointers. Jim justly noted that this is a good
opportunity to clean up the variable names as well.
I went over all the changes to ensure my find-and-replace didn't have
any undesired side-effects. I hope I didn't miss any, but if you end up
at this commit doing a git blame on a weirdly named variable, please
know that the change was unintentional.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This patch removes the comments grouping header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

Replace calls to LLVM's is_directory with calls to LLDB's FileSytem
class. For this I introduced a new convenience method that, like the
other methods, takes either a path or filespec. This still uses the LLVM
functions under the hood.

These three classes have no external dependencies, but they are used
from various low-level APIs. Moving them down to Utility improves
overall code layering (although it still does not break any particular
dependency completely).
The XCode project will need to be updated after this change.

Summary:
This is a clean version of the change suggested here: https://bugs.llvm.org/show_bug.cgi?id=37495
The main change is to follow the same pattern as non-windows targets and use an unwinder object to retrieve the register context. I also changed a couple of the comments to actually log, so that issues with unsupported scenarios can be tracked down more easily. Lastly, ClearStackFrames is implemented in the base class, so individual thread implementations don't have to override it.

If we have a function with signature f(addr_t, AddressClass), it is easy to muddle up the order of arguments without any warnings from compiler. 'enum class' prevents passing integer in place of AddressClass and vice versa.

Most non-local includes of header files living under lldb/sources/
were specified with the full path starting after sources/. However, in
a few instances, other sub-directories were added to include paths, or
Normalize those few instances to follow the style used by the rest of
the codebase, to make it easier to understand.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap

import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)

Now, if DoReadMemory or DoWriteMemory encounters error then return 0

the previous fix did not work because of different const qualifications

struct iovec is used as an interface to system (posix) api's. As such,
we shouldn't be using it in os-independent code, and we shouldn't be
defining our own iovec replacements.
Fortunately, its usage was not very widespread, so the removal was very
easy -- I simply moved a couple declarations into os-specific code.

This is the FreeBSD equivalent of r238549.
This serves 2 purposes:
* LLDB should handle inferior process signals SIGSEGV/SIGILL/SIGBUS/
SIGFPE the way it is suppose to be handled. Prior to this fix these
signals will neither create a coredump, nor exit from the debugger
or work for signal handling scenario.
* eInvalidCrashReason need not report "unknown crash reason" if we have
a valid si_signo

strerror is not thread-safe. llvm's StrError tries hard to retrieve the
string in a thread-safe way and falls back to strerror only if it does
not have another way.

In the absense of a more specific handler for TRAP_CAP (generated by
ENOTCAPABLE or ECAPMODE while in capability mode) treat it as a trace
trap. Obtained from FreeBSD r318884.
We should later add an option to have LLDB control the trapcap procctl
(as with ASLR), as well as report a specific stop reason. For now this
change eliminates an assertion failure from LLDB.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

Summary:
The files there can always be referred to using their full path, which
is what most of the code has been doing already, so this makes the
situation more consistent. Also fix the the code in the FreeBSD plugin
to use the new paths.

Summary:
GetAuxvData was causing dependencies from host to target and linux
process modules. It also does not fit netbsd use case, as there we can
only read the auxiliary vector with ptrace, which is better done in the
process plugin, with the other ptrace calls.
I resolve these issues by moving the freebsd and linux versions into the
relevant process plugins. In case of linux, this required adding an
interface in NativeProcessProtocol. The empty definitions on other
platforms can simply be removed.
To get the code compiling I had to add ProcessGdbRemote -> ProcessLinux
dependency, which was not caught before because we depended on it
transitively.

It seems sysctl.h is not self-contained, as I get missing symbols in the
header itself now. I am going to include all files that the file I moved
this from included, and hope that is enough.
llvm-svn: 298063
Summary:
These classes existed only because of the GetName() static function,
which can be moved to a more natural place anyway. I move the linux
version to NativeProcessLinux (and get rid of ProcFileReader), the
freebsd version to ProcessFreeBSD (and fix a bug where it was using the
current process ID, instead of the inferior pid), and remove the NetBSD
version (which was probably incorrect anyway, as it assumes the current
process instead of the inferior.
I also add an llgs test to that verifies thread names are read
correctly.
